ECC 6 with EHP system copy

Question

Hi,
Just a little question :
We Are on a Windows MSSQL environnement
did a fresh upgrade of our landscape ECC6 old SP -> EHP4 stack 5
made a copy of our system -> update on this copy
now I'd like to do 2 things
1 copy of the updated system on a blank computer with different SID (did not have QUAL and I'd like to create one by copying )
2 refresh the original system
For point 1
I thought about doing a basic Sapinst system copy, but everytime I did this before I was using a Installation MasterDVD containing kernel and system description file (xml)
How could I do that ?
What should be the process ? 
for point 2 I have in mind to :
stop the instance
detach the DB
replace the old kernel files with  the up to date kernel (copy /usr )
attach a copy of the up to date db
Will it work? What should be the process ?

Hello Edouard,
copy of the updated system on a blank computer with different SID
It is better to use SAPINST to do a system copy as your SID changes. The SAPINST will take care of the SID updation in SAP as well as in MS SQL DB.
I did this before I was using a Installation MasterDVD containing kernel and system description file (xml)
If u have the latest kernel downloaded from SAP SMP, you can use that kernel itself by mapping the path in the section SAP Syetem > Unpack Archives in the SAPINST. This will extract the new kernel into the kernel directory and thus avoiding one more manual activity to upgrade the kernel.
stop the instance
detach the DB
replace the old kernel files with the up to date kernel (copy /usr )
attach a copy of the up to date db
If u r following the afore mentioned steps, this may become unnecessary.
Hope this will definitely help you.
Good Luck. I hope to here from u whether this helped u or not.
